A mold form for molding balloons includes a mold form body having multiple linear appendages which extend from the mold form body to create body portions of the balloon. Upon inflating the balloon, the body portions created by the appendages form portions of a shape or features similar to some recognizable object. The appendages on the mold form body are arranged to extend from the mold form body in a way that allows the balloon to be removed from the mold form body using conventional mass manufacturing techniques, but which also produce body portions of the balloon at locations on the balloon, and at angles which allow the body portions to resemble familiar shapes rather than a conventional balloon shape.

An orthopedic precast comprises a knitted shell portion and a knitted flexible portion. The precast is positioned about a limb or other mold, and heat or other hardening agent is used to harden the shell portion, while retaining flexibility in the flexible portion. Contemplated hardening agents include light, heat, and chemical polymerizing agents. In some embodiments the shell portion includes threads or yarns comprising a thermoplastic, which is then hardened by heating the thermoplastic sufficiently to at least partially melt, and thereby fuse together some of the threads or yarns, and then cooling to ambient temperature. In other embodiments, the precast is contained in a bag or other airtight container, along with a self-heating composition that is triggered to release heat upon contact with oxygen. In still other embodiments, the precast includes a prepolymer of other polymerizable composition, which is polymerized by effective application of light, heat, and/or chemical agent(s).

A surgical glove mold set, comprising a plurality of surgical glove mold-forms, wherein each surgical glove mold-form of the plurality of surgical glove mold-forms includes a common palm width (PW) and different finger lengths.

Provided among other things is a glove formed by latex dipping having one or more textured finger tips wherein: the texture at the finger tips results from forming the glove on a former having the following properties: TABLE-US-00001 (micrometer) Ra Av. roughness about 7-14 Rsm Mean width of roughness about 500-720 Rpc Peak count about 15-20
the glove being non-chlorinated, wherein the glove is a (i) single dip nitrile glove or (ii) a dipped glove with a textured layer formed of polymer latex, and comprising a multivalent metal ion salt of an organic acid with log P of about 4 to about 15.

Cauls and methods of using cauls to produce composite articles are provided. The caul transitions from a rigid state to an elastomeric state and from an elastomeric state to a rigid state in response to a stimulus and has a reinforcement density of from 100 kg/m.sup.3 to 500 kg/m.sup.3. Methods of using cauls to produce composite articles involve positioning one or more fiber layers between a caul and a cure mold surface when the caul is in a rigid state. The fiber layers, caul, and cure mold surface may be covered with a sealed barrier and a pressure gradient may be applied. Before, after, or before and after performing the vacuum the fiber layers may be impregnated with resin. The fiber layers may be cured, which may provide a stimulus to transition the caul from a rigid to an elastomeric state, and the composite article is produced.

A container structure having one or more sections and a method for manufacturing such a structure is provided. Using an additive manufacturing process, a mold material is applied to produce a shaped substrate in the form of the desired sections and/or structure. Multiple reinforcement members are disposed within the substrate and extend between and are at least partially exposed at the inner and outer substrate surfaces. A coating material is applied to the inner and outer substrate surfaces and bonds to the exposed portions of the reinforcement members. The mold material is removed and replaced with another material among the reinforcement members between the substrate coatings.
